The way the button is setup, is that there are a couple of rad buttons inside a rad tree list, of which is in a user control, and the usercontrol is inside a rad wizard, and finally the rad wizard is inside an rad ajax panel. I tested the wizard with the buttons locally on my machine and pushed it online and I have no issues. However, I am getting error emails that it seems to be throwing an error on the rad button, with a couple of other users. So far I only received two of the errors in the control. So I am unsure as to why it would be throwing an error. Would any one know why it worked for me but it threw these errors on a couple of users?
Here are a couple of the stack trace errors:
System.ArgumentException: Invalid object passed in, ':' or '}' expected.

We are not aware of the mentioned issue and actually you are the first one to report it. Can you tell us whether you are using the latest official version - 2016.1.113 and if not does upgrading to it help?
You can also try to disable the AJAX and see whether the issue is caused due to improper AJAX settings. You can examine the following resources for details on the matter:
- http://demos.telerik.com/aspnet-ajax/ajaxpanel/overview/defaultcs.aspx
- http://demos.telerik.com/aspnet-ajax/ajaxpanel/application-scenarios/loading-usercontrols/defaultcs.aspx
If the above information, however, do not help it would be better to try to reproduce the problem in a runnable sample and then provide it back to us. If, however, that is not possible you can send us at least the problematic code and/or a live URL of the page.

I get about one of these per day. Here is an example:
Unterminated string passed in. (5022): {"enabled":true,"emptyMessage":"","validationText":"~~~private text~~~","lastSetTextBoxValue":"~~~private text, but that is truncated~~~I cannot reproduce it myself, but our production server has several of these per week. I have replaced the actual text values with ~~~private text~~~ since I don't want to share the client information in there, but interestingly, the "lastSetTextBoxValue" is almost always truncated (and these tend to be long RadTextNox fields that are TextMode="MultiLine").
Here is the stack trace:

You can also try the following:
- Disable AJAX by setting the EnableAJAX property of RadAjaxManager to false. If you are usingUpdatePanel - remove it. See if the behavior changes after this.
- Disable RadCompression if it is enabled.

Was there a resolution found for this issue? The project I am working on is having the same sporadic symptoms.
RadCompression is not enabled.
Some of the controls that have triggered this issue are in RadAjaxPanels or UpdatePanels, while others use javascript to make ajax calls.
We have never been able to get the problem to duplicate

Hi Tory,
Usually, such issues are observed when there are nested AJAX panels on the page. When two AJAX requests are triggered at the same time, they cancel each other and breaks the functionality of the page (throwing JS errors, etc.). Can you make sure that there are no such nested update panels at your end?
In addition, we strongly recommend not using all AjaxUpdatePanels, UpdatePanels and AjaxManager at the same time in order to avoid issues like that. You can solve that by replacing the Ajax and Update panels with asp:Panels, adding the later to the update settings of the AjaxManager after that.

Vessy
